One of the most uncomforable things was starting a rowing race with one of your boys not quite adjusted right.

Basically, you can feel it being squashed by your legs at the end of each stroke because there's no way to adjust once the race has started without actually stopping (which is basically impossible in anything other than a single scull). If it happens, you know that you've got at least 6/20 minutes of discomfort ahead before you even consider the pain from the race itself
